Consider a source moving towards an observer at the speed \( \left(v_{\mathrm{S}}\right) \) of \( 95 \% \) that of sound \( (v) \). Deduce the observed frequency, if the original frequency is \( 500 \mathrm{~Hz} \). (Think what would happen, if \( v_{\mathrm{S}}v \) ? Jet planes moving faster than sound are so common.
